Researchers at Sandia National Laboratories have developed a portable X-ray device that can detect explosives and objects in packages using reflected, rather than transmitted, X-rays. The device is designed to be safer for law enforcement officers and can transmit partial images useful in police work even if the package explodes.
Researchers found that about 6% of children exhibit a strong tendency towards revenge in minor conflicts, indicating poorer friendships. This goal was the most predictive factor of their friendship situation in real life, highlighting the need to understand and address this behavior.
A study by Duke University Medical Center scientists found that habitual coffee drinkers experienced increased adrenaline, noradrenaline, and blood pressure when consuming caffeine. This heightened response can lead to damage in the heart over time.
Researchers developed a new mathematical expression that accurately models p-n junction performance, resolving past misconceptions. The theory reveals unexpected results, including the diffusion capacitance vanishing for long diodes.
Scientists are modifying bee venom to develop cancer treatments with fewer side effects than traditional drugs. The goal is to create immunotoxins that target cancer cells specifically, overcoming major drawbacks of chemotherapy.
Scientists have confirmed that a protein complex, when defective, causes limb girdle muscular dystrophy. Researchers developed a cell culture system to mimic the defect and found that complete assembly of the sarcoglycan complex is dependent on simultaneous synthesis of all four sarcoglycans.
A Johns Hopkins-led study shows that many heart disease features are better explained by the body's responses to genetic damage rather than the damage itself. The research used a miniaturized catheter to compare healthy and diseased mouse hearts, revealing evolving adaptations that worsen symptoms over time.
